Question

A bicycle is sold at a gain of 16% if it had been sold for rs 20 more 20% have gaoned what is cp

Answer 1

Solution:-
Let the Cp be x.
Sp at gain of 16℅
$= > \frac{116}{100}x$
Sp at gain of 20℅
$= > \frac{120}{100}x$
A/q
$\frac{120}{100} x - \frac{116}{100}x = 20$
$\frac{120 - 116}{100} = 20$
$\frac{4}{100} x = 20$
$x = \frac{20 \times 100}{4}$
$x = 500$
Hence,the Cp of the bicyle is ₹500
